swarmctl -b Largest streams

swarmctl -b returns the largest streams and the associated replica counts.
- Add -a for all nodes.
- -x for much more output to file.
If the largest stream on a particular disk is a segment, that is noted as "seg"
/dev/sdb on 172.30.13.33 is retired in the example below:

[root@linux dist]# ./swarmctl -a -b -d 172.30.13.45
